UNITED STATES Application led May 5, 1922.

This invention relates to bottle filling means.

The invention has for an object to provi-dc for the rapid filling ofvarious types of receptacles and is shown in the present case asdesigned for the iilling of milk bottles. Y'

It is another object ot' the invention to provide a device which willenable the rapid iilling or charging of receptacles with a hquid andwhich provides for the venting or" the receptacle while it is being`filled.

Again, an object is to provide means for concurrently opening a valvewhen the device is applied to a bottle month sothat liquid can flowcontinuously through the device into the bottle, and which device willprovide for the displacement of the air.

In my milk bottle filler I incorporate a valve cage with a float valvein an air-vent pipe which is enclosed in a shell through which milk maybe conducted to the bottle. This cage is secured tothe upper end of theshell, being held in place by a. vent tube or sleeve to which the handleis directly attached. A shoulder formed in the shell holds both theair-vent pipe and thevalve cage inv position. lVhen the bottle is filledthe milk iows up the air vent tube, oats the valve in the valve cage onthe upper end of this tube and thereby prevents any more milk fromiiowing into the bottle.

'Vhen the handle is raised the valve at the lower end of the nozzlemember, .duel to the telescopic arrangement, closes the nozzleand shutsoil the milk from the source otsupply, so that the filler may betransferred from bottle to bottle. However, in lifting the filler themilk in the air-vent tube', between its lower end and the float valve,will flow downwardly into the bottle and hence fill the bottle to thebrim by flowing a suilicient quantity ot milk to till the space occupiedor displaced by the lower'end of the filling nozzle and the valve toclose sucli nozzle. n i

An embodiment or the invention is" described in the followingspecification and illustrated in the accompanying drawings, iniwhichFig. 1 is a side elevation of the device as applied to a bottle, aportion or which is in section.

Fig. 2 is a longitudinal section through the device showing it in closedposition upon the bottle mouth.

serial No. 558,623.

Fig. 3 is a sectional view showing the valve 1n open position andindicating the escape of air while the bottle is iilling.

Fig. 4 is a sectional view of the valve similar to Fig.l 3, with thevalve closed stopping the iiow of milk.

The invention is embodied in a form of device vdesigned lto beconstantly in flexibly connected relation to a source ot' supply ont:liquid such, for instance, as milk, andA the device is adapted to bequickly shifted from one bottle or other receptacleto another to enablethe rapid filling of the bottles from the source of supply. A purpose oftheinvention is to provide 'means for eliminating waste and at the sametime to secure sanitary service and operation.

Means are also provided for automatically cutting off the outiiowthrough the air vent in case that the filling nozzle, as it may betermed, is not closed ott at the proper instant and thus obviates thespilling of the liquid. i

The nozzle or filling device consists of an elbow like shell 2, onebranch 3 of which is designed to be fitted to a supply source as'bymeans of a flexible tube 4 connected to the reservoir containing theliquid with which receptacles are to be charged. The lower end of theshell 2 is shown'as turned down and slidably receives a nozzle member 5having` an` annular outer shoulder 6 against whiclr bears downwardly a`spring 7, the upper end ofv which seats on a shoulder or the shell 2.The upper end of the shell is internally threaded at 8 to receive asleeveorvent tube 9 to the Vupper end of which may be suitably secured ahandle yoke 10 providedwith atransversehandle bar 11.

The' vent tube 9 encloses a bushing 1Q, having an outturnedllange 13 inthe end of the shell 2 and bearing upon a flange 14 provided on theupp'e'rend of an inner air pipe 15 which is secured in place by thebusliiuglQ and the tube 9. The pipe 15is spaced within the b'ore of theshell 2 and extends below the" lower end theieof and carries a valveforming disc or washer 16 which is clamped in place,l by'a head 17screwed on the end of the pipe 15. The head 17 is shown as provided witha plurality of apertures 17a which permit the escape of air upwardlythrough the pipe 15 and out through the tube 9. On the upper end of thepipe 15 is placed a valve ball 18, which is designed to rise and bearupon a seat 12a provided therefor in the bushing or valve seat member12.

The ball 18 is of such weight that it will not be lifted by the airflowing upwardly but will be floated on the liquid rising in the pipe15.

Surrounding the lower is a cushion member 2O of material such as rubber,and this is provided with a conical lower surface adapted to be readilyapplied to the mouth end of a receptacle as a. bottle B.

In use of the device, the operator simply applies the cushion member 20to the bottle to be charged and then presses down upon the handle bai11, which causes a downward sliding movement of the shell 2 through thesleeve which is supported by the yielding member 2O bearing on thebottle. The downward movement of the' sleeve results in end of the shell2 the downward movement of the air pipe 15 and the removal of the valvedisc16 from tne lower end of the sleeve .5.

down through the filling device into the bottle. As the liquid reaches apredetermined level in the bottle, release of pressure l2a and cut offthe flow of liquid. During the filling of the bottle the air would befree to pass the ball 12 and escape through the vent tube 9. Y I

From the above it will beseen that l'have provided a simple,substantial, and pracvtieable form of lling nozzley whereby a largenumber of receptacles to be filled can berapidly charged, one'after theother, by the mere shifting of the nozzle from mouth to mouth of thevarious receptacles. It will be seen that the cushion member 20 isnotremoved from the bottle mouth until after the valve 16 has closedsince the spring holds the stopper like member 2O in place whilepressure is being removed from the handle 11.

lt will thus be seen that lwhen the bottle filler-fis lifted, themillrtrapped in the vent tube between its lower end and the float valve V118will flow downwardly into the Y bottle and fill the space occupiedl bythe softor yieldable `This allows theV liquid from the supplytube l toflow readily cushion member on the end of the nozzle and the valveattached to the lower end of the airpipe 15. rl`lie various elements areso proportioned that thismilk will fill the `bottle substantially to thebrim and therefore eliminate the necessity of a subsequent operation toVfill this small amount of millr into the bottle to give correct andfull Y between the studs for the upward flow of air as indicated in Fig.3. However, 'when the milk rises in the tube 15 the ball floated upagainst the seat 1:2EL as shown in Fig. 4.

Various modifications and changes may be resorted to within the spiritof the inveir tion as claimed.

What is claimed is: f

1. A bottle filler comprising-in combination a tubular shell having alateral branch adapted to be 4fitted to a source of supply,

a nozzle slidably mounted on the lower end of the shell, a compressionspring between the nozzle and the shell, a vent tube extend-` ingupwardlyfrom the top of the shell, a

handle attached thereto, an air vent pipe extending through the shelland connected to the upper end thereof, the connection Y forming a topclosure for the shell, a float valve oiithe'upper end of the air ventpipe adapted to discharge into the air vent tube 'but prevent flowing ofliquid therein.

2. A bottle filler comprising in combination a` tubular shell, a lateralbranch adapted to befitted to a source of supply, a nozzle slidablymounted on the lower end of the slielhaco'mpression spring between thenoz-V zle and the shell, a vent pipe extending through the shellfand thenozzle having a flangeon its upper end, abushing resting on the flange,a vent tube outside the bushing connected to the shell, a ball valvehaving a valve seat in the upper part of the'bushing,

a series of studs with spaces therebetween on the flange and a ball inthe bushing adapted to'V rest on the studs and to float against thevalve seat.

In testimony whereof l have signed my name to this specification.V
